Mysql 常见错误
[Err] 1055 - Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated column 'information_schema.PROFILING.SEQ' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
修改.ini 配置 sql_mode='NO_ENGINE_SUBSTITUTION' 然后重启服务
